-# This Dockerfile can be used to build a docker image. 
-# Docker containers of this image can be used to build EosSdk applications.
-# The following build options are provided:
-#       arch : Use 'm32' to build a 32-bit EosSdk application otherwise use 'm64'
-#              to build a 64-bit EosSdk application.
-#              Default value is set to 'm32'.
-# Example:
-# Steps to build an application using EosSdk docker container.
-# 1) Build Docker image with tag as arista-eossdk:latest:
-#    a) Docker image with a 32-bit libeos.so
-#       "docker build -t arista-eossdk --build-arg arch=m32 ."
-#       or "docker build -t arista-eossdk ."
-#       
-#    OR
-#    b) Docker image with a 64-bit libeos.so
-#       "docker build -t arista-eossdk --build-arg arch=m64 ."
+# This Dockerfile can be used to build a docker image that can then be used to create
+# a docker container that will be able to compile EosSdk applications in exactly the
+# same way as EOS native applications are compiled (and thus binary compatible with
+# EOS libraries).
 #
-# 2) Run Docker container:
-#    docker run -v /home/sdk-app:/sdk-app --name <name> -it arista-eossdk bash
-#    This will mount /home/sdk-app as sdk-app inside the container.
-#    Place the application code and necessary dependencies in /home/sdk-app
+# 1) Build Docker image (we will call it 'arista-eossdk')
+#  docker build . -f <this Dockerfile> -t arista-eossdk
 #
-# 3) Compile application binary:
-#    Run the following command from /sdk-app.
-#    For 32-bit binary: "g++ -m32 --std=gnu++0x -o <target> <source file> -leos"
-#    For 64-bit binary: "g++ -m64 --std=gnu++0x -o <target> <source file> -leos"
-#    The generated binary will also be available in /home/sdk-app on the host
-#    machine.
+# 2) Create container: (assuming application code to be compiled is at /code on the
+#    host machine that starts the container)
+#  docker run -v /code:/code -itd --name arista-eossdk-c1 arista-eossdk
 #
-#4) Load the application on Arista switch:
+# 3) Go into the container and build the application
+#  docker exec -it arista-eossdk-c1 /bin/bash
+#  cd /code
+#  g++      -std=gnu++20 -o /code/build/HelloWorld.o -c /code/HelloWorld.cpp
+#  g++      -std=gnu++20 -o /code/build/HelloWorld      /code/HelloWorld.o  -leos -lrt
+#  g++ -m32 -std=gnu++20 -o /code/build/HelloWorld.o -c /code/HelloWorld.cpp
+#  g++ -m32 -std=gnu++20 -o /code/build/HelloWorld32    /code/HelloWorld.o  -leos -lrt
+#
+# 4) Load the application (in /code/build on your host) onto an Arista switch
 #    Further instructions to run the application on Arista switch can be found here:
 #    https://github.com/aristanetworks/EosSdk/wiki/Quickstart%3A-Hello-World
 #
+# 5) Cleanup
+#    docker rm arista-eossdk-c1
+#    docker rmi arista-eossdk
